针对1-氨基-2-茶酚-4-磺酸作还原剂测定工业循环冷却水中的二氧化硅含量时对环境造成污染的问题，采用抗坏血酸作还原剂，不仅保证了测定精度，而且有效地降低了对环境的污染。
The problem of contamination of the environment when 1-amino-2-hydroxy-2-hydroxy-4-sulfonic acid is used as a reducing agent for measuring the silica content in industrial circulating cooling water is not only ensured by the ascorbic acid as a reducing agent but also effective Reduce the pollution of the environment.
